Green function region of convergence nonlinear differential equation












0












$begingroup$


Given a second order nonlinear differential equation with the boundary values:



$y'' + frac{1}{x}y' + y^2 = 0$, with $y'(0)= 0, y(1)=1$



How would one estimate the region of convergence given by:



$$max_{x,t exists <0,1>}|G(x,t)|max_{y exists (-inf,inf)}f'(y) < 1$$



Any reference would be welcome because I'm new to Green functions.

    Could you add of what sequence you consider the convergence? And what is the linear operator you construct the Greens functions for? Just the first two terms?
